SAN FRANCISCO – Barry Bonds said he did not get amphetamines from teammate Mark Sweeney, but did not deny a report Thursday saying he tested positive for the drugs last season.

According to a story in the New York Daily News, the San Francisco slugger failed an amphetamines test in 2006. The newspaper reported that when first informed of the positive result, Bonds attributed it to a substance he had taken from Sweeney’s locker.

Thursday, Bonds did not deny that but did apologize to Sweeney.

“He is both my teammate and my friend,” Bonds said in a statement. “He did not give me anything whatsoever and has nothing to do with this matter, contrary to recent reports.

“I want to express my deepest apologies especially to Mark and his family as well as my other teammates, the San Francisco Giants organization and the fans,” he said.

That’s all the Giants star, shadowed by steroids allegations and only 22 home runs from breaking Hank Aaron’s career home run record, said about the alleged positive drug test. Bonds has steadfastly denied used performance-enhancing drugs.

Bonds’ reported positive test could be another snag in contract negotiations with the Giants. The sides reached a preliminary agreement on a $16 million, one-year contract Dec. 7, but the seven-time NL MVP still hasn’t signed the deal or taken the mandatory physical that is part of the process.

The sides have been working to finalize complicated language in the contract that concerns the left fielder’s compliance with team rules, as well as what would happen if he were to be indicted or have other legal troubles.

There’s a long history of amphetamines – or speed and more commonly called “greenies” in the baseball world – fueling generations of baseball players.
